The pidfd_test selftest passes. Ran the io_uring example from fio, which prints lots of: IOPS=209952, IOS/call=32/32, inflight=117 (117), Cachehit=0.00% IOPS=209952, IOS/call=32/32, inflight=116 (116), Cachehit=0.00% IOPS=209920, IOS/call=32/32, inflight=115 (115), Cachehit=0.00% IOPS=209952, IOS/call=32/32, inflight=115 (115), Cachehit=0.00% IOPS=209920, IOS/call=32/32, inflight=115 (115), Cachehit=0.00% IOPS=209952, IOS/call=32/32, inflight=115 (115), Cachehit=0.00% IOPS=210016, IOS/call=32/32, inflight=114 (114), Cachehit=0.00% IOPS=210016, IOS/call=32/32, inflight=113 (113), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=113 (113), Cachehit=0.00% IOPS=210016, IOS/call=32/32, inflight=113 (113), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=112 (112), Cachehit=0.00% IOPS=210016, IOS/call=32/32, inflight=110 (110), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=105 (105), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=104 (104), Cachehit=0.00% IOPS=210080, IOS/call=32/32, inflight=102 (102), Cachehit=0.00% IOPS=210112, IOS/call=32/32, inflight=100 (100), Cachehit=0.00% IOPS=210080, IOS/call=32/32, inflight=97 (97), Cachehit=0.00% IOPS=210112, IOS/call=32/32, inflight=97 (97), Cachehit=0.00% IOPS=210112, IOS/call=32/31, inflight=126 (126), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=126 (126), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=125 (125), Cachehit=0.00% IOPS=210016, IOS/call=32/32, inflight=119 (119), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=117 (117), Cachehit=0.00% IOPS=210016, IOS/call=32/32, inflight=114 (114), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=111 (111), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=108 (108), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=107 (107), Cachehit=0.00% IOPS=210048, IOS/call=32/32, inflight=105 (105), Cachehit=0.00% Which is good I think? cheers
